SOCS3 overexpression enhances ADM resistance in bladder cancer T24 cells.	OBJECTIVE: JAK-STAT3 signaling pathway widely participates in cell proliferation and apoptosis. Suppressor of cytokine signaling 3 (SOCS3) is a negative regulator of JAK-STAT3. SOCS3 downregulation is associated with drug resistance in breast cancer and leukemia. However, its role in bladder cancer drug resistance is still unclear. This study established ADM resistant bladder cancer cell model to investigate the role of SOCS3-JAK/STAT3 signaling pathway ADM resistance. MATERIALS AND METHODS: ADM drug resistant cell line T24/ADM was established. SOCS3, p-JAK2, p-JAK3, and Bcl-2 expressions in T24/ADM, T24, and HBEC cells were compared. Cell proliferation and apoptosis were evaluated by flow cytometry. T24/ADM cells were divided into five groups, including control, pSicoR-blank, pSicoR-SOCS3, FLLL32, and pSicoR-SOCS3 + FLLL32 groups. Cell proliferation was determined by EdU staining. RESULTS: SOCS3 was reduced, while p-JAK2, p-STAT3, and Bcl-2 expressions upregulated in T24 cells compared with HBEC cells. T24/ADM cells exhibited lower SOCS3, higher p-JAK2, p-STAT3, and Bcl-2 levels than T24 cells. Cell apoptosis was higher, whereas cell proliferation was weaker in T24 cells compared with T24/ADM cells. SOCS3 overexpression and/or FLLL32 treatment significantly downregulated p-JAK2, p-STAT3, and Bcl-2 expressions, attenuated cell proliferation, and elevated sensitivity to ADM induced cell apoptosis. CONCLUSIONS: SOCS3 reduction was associated with bladder cancer sensitivity to ADM. SOCS3 overexpression decreased JAK-STAT3 signaling pathway activity, declined Bcl-2 expression, inhibited cell proliferation, elevated cell apoptosis, and enhanced ADM sensitivity in T24 cells.	bladder
Analysis of Clinicopathological Features and Prognostic Factors in 39 Cases of Bladder Neuroendocrine Carcinoma.	AIM: Through analysis and summarization of clinicopathological features, immunohistochemical expression, pathological diagnostic criteria, prognostic and other factors in patients suffering from bladder neuroendocrine carcinoma (BNEC), a better understanding of BNEC could be achieved to provide solid evidence for clinicopathology and prognosis. MATERIALS AND METHODS: The clinicopathological data of 39 cases of BNEC with up to 5-year follow-up data (median follow-up=650 days) were analyzed retrospectively based on immunohistochemical staining. Survival analyses were carried out using the Kaplan-Meier method and tested with the log-rank method. Multivariate Cox regression analysis was adopted to screen independent risk factors affecting patients' survival. In these 39 cases of BNEC, there were 26 cases of male patients, 13 female, with the proportion of male to female being 2:1. The ages of onset ranged from 44 to 86, with the median age being 62 and the average age 61.97 years, respectively. Histologically, referring to the WHO standard of neuroendocrine lung tumor classification, there were 7 cases of typical carcinoid tumors, 8 atypical carcinoid, 12 small-cell carcinomas and 12 large-cell carcinomas. In these cases there were 11 cases of featured urothelium carcinomas and 9 cases of adenocarcinomas. RESULTS: Immunohistochemical staining showed that, in these 39 cases of BNEC, the positive expression for the neuroendocrinic markers, including neural cell adhesion molecule 56 (CD56), synaptophysin (Syn), chromogranin A (CgA), neuron-specific enolase (NSE), thyroid transcription factor-1 (TTF-1), cytokeratin (CK) and cytokeratin 7 (CK7), accounted for 39/39, 27/39, 18/39, 39/39, 19/39, 10/39 and 8/39, respectively. In contrast, cytokeratin 20 (CK20), protein 63 (P63), human melanoma black 45 (HMB45), S-lfln protein 100 (S-100) and leukocyte common antigen (LCA) were all negatively expressed. During the follow-up period, 12 patients died. The 1-, 3- and 5-year overall survival (OS) rates were 76.92%, 74.36% and 69.23%. CONCLUSION: BNEC is one of the most malignant tumors with severe invasiveness and poor prognosis. Immunohistochemistry revealed that CD56, Syn, CgA, NSE, TTF-1, CK, CK7, CK20, P63, HMB45, S-100 protein and LCA immune markers play important roles in diagnosis and differentiation. Many factors, including the patient's age, size and shape of the tumor, operative method, perineuronal invasion, vascular invasion, distant organ metastasis and pathological type, show great difference in influencing OS time of patients, among which the size of the tumor, no invasion, vascular invasion and distant organ metastasis are independent risk factors affecting prognosis (survival time). Radical cystectomy is the prior alternative to treat this tumor.	bladder
The Burden of Cystoscopic Bladder Cancer Surveillance: Anxiety, Discomfort, and Patient Preferences for Decision Making.	OBJECTIVE: To examine discomfort, anxiety, and preferences for decision making in patients undergoing surveillance cystoscopy for non-muscle-invasive bladder cancer (NMIBC). METHODS: Veterans with a prior diagnosis of NMIBC completed validated survey instruments assessing procedural discomfort, worry, and satisfaction, and were invited to participate in semistructured focus groups about their experience and desire to be involved in surveillance decision making. Focus group transcripts were analyzed qualitatively, using (1) systematic iterative coding, (2) triangulation involving multiple perspectives from urologists and an implementation scientist, and (3) searching and accounting for disconfirming evidence. RESULTS: Twelve patients participated in 3 focus groups. Median number of lifetime cystoscopy procedures was 6.5 (interquartile range 4-10). Based on survey responses, two-thirds of participants (64%) experienced some degree of procedural discomfort or worry, and all participants reported improvement in at least 2 dimensions of overall well-being following cystoscopy. Qualitative analysis of the focus groups indicated that participants experience preprocedural anxiety and worry about their disease. Although many participants did not perceive themselves as having a defined role in decision making surrounding their surveillance care, their preferences to be involved in decision making varied widely, ranging from acceptance of the physician's recommendation, to uncertainty, to dissatisfaction with not being involved more in determining the intensity of surveillance care. CONCLUSION: Many patients with NMIBC experience discomfort, anxiety, and worry related to disease progression and not only cystoscopy. Although some patients are content to defer surveillance decisions to their physicians, others prefer to be more involved. Future work should focus on defining patient-centered approaches to surveillance decision making.	bladder
Level of mitoses in non-muscle invasive papillary urothelial carcinomas (pTa and pT1) at initial bladder biopsy is a simple and powerful predictor of clinical outcome: a multi-center study in South Korea.	BACKGROUND: Histologic grade is the most important predictor of the clinical outcome of non-muscle invasive (Ta, T1) papillary urothelial carcinoma (NMIPUCa), but its ambiguous criteria diminish its power to predict recurrence/progression for individual patients. We attempted to find an objective and reproducible histologic predictor of NMIPUCa that correlates well with the clinical outcome. METHODS: A total of 296 PUCas were collected from the Departments of Surgical Pathology of 11 institutions in South Korea. The clinical outcome was grouped into no event (NE), recurrence (R), and progression (P) categories. All 25 histological parameters were numerically redefined. The clinical pathology of each case was reviewed individually by 11 pathologists from 11 institutions based on the 2004 WHO criteria and afterwards blindly evaluated by two participants, based on our proposed parameters. Univariate and multivariate logistic regression analyses were performed using the R software package. RESULTS: The level of mitoses was the most reliable parameter for predicting the clinical outcome. We propose a four-tiered grading system based on mitotic count (> 10/10 high-power fields), nuclear pleomorphism (smallest-to-largest ratio of tumor nuclei >20), presence of divergent histology, and capillary proliferation (> 20 capillary lumina per papillary core). CONCLUSIONS: The level of mitoses at the initial bladder biopsy and transurethral resection (TUR) specimen appeared to be an independent predictor of the Ta PUCa outcome. Other parameters include the number of mitoses, nuclear pleomorphism, divergent histology, and capillary proliferation within the fibrovascular core. These findings may improve selection of patients for a therapeutic strategy as compared to previous grading systems.	bladder
Functioning metastatic paraganglioma of the urinary bladder in a 10-year-old child.	Paragangliomas of the urinary bladder are very rare tumours representing less than 1% of bladder tumours. Preoperative diagnosis is essential to avoid perioperative complications related to catecholamine release. A high index of suspicion should be maintained when the classical symptoms of voiding-related paroxysms of headache, palpitation and dizziness are present. We present a rare case of malignant paraganglioma of the urinary bladder in a 10-year-old boy. The patient had the classic presentation. We review the radiological diagnostic tools and findings of this rare entity.	bladder
Urothelial cell carcinoma after BK polyomavirus infection in kidney transplant recipients: A cohort study of veterans.	BACKGROUND: BK polyomavirus (BKPyV) reactivation is a common clinical occurrence in kidney transplant recipients (KTR). Several other polyomaviruses have been implicated as pathogens with a direct role in the development of malignancies, raising the question of whether BKPyV might also be oncogenic. METHODS: This study is the first retrospective, multicenter cohort study evaluating the relative risk for urothelial cell carcinoma (UCC) associated with BKPyV infection among KTR, and was conducted among veterans who underwent transplantation between 2000 and 2009. BKPyV cases were defined as those veterans with any clinical evidence of BKPyV infection, including positive polymerase chain reaction testing of urine and/or serum for BKPyV or kidney biopsy showing BKPyV-associated nephropathy. RESULTS: Among the 646 veterans who met inclusion criteria for the study, 103 had clinical evidence of BKPyV infection (16%). The overall relative risk for developing any malignancy after BKPyV infection was 1.13 (95% confidence interval [CI] 0.89-1.44). The adjusted relative risk for malignancy after BKPyV infection was greatest with UCC (8.21, 95% CI 0.75-89.7) and with metastatic disease of unknown etiology (8.21, 95% CI 0.75-89.7). The screening prevalence for BKPyV infection increased from 18% for those veterans who underwent transplantation in 2000 to 86% for those veterans who underwent transplantation in 2009, during which time the measured prevalence of BKPyV infection increased from 7% to 24%. CONCLUSION: In this cohort of KTR veterans, no overall increased or decreased relative risk for malignancy was associated with evidence of prior BKPyV infection. A >8-fold increased risk of developing UCC after BKPyV infection was seen, although this risk was not found to be statistically significant.	bladder
Alcohol consumption and risk of urothelial cell bladder cancer in the European prospective investigation into cancer and nutrition cohort.	Findings on the association between alcohol consumption and bladder cancer are inconsistent. We investigated that association in the European Prospective Investigation into Cancer and Nutrition cohort. We included 476,160 individuals mostly aged 35-70 years, enrolled in ten countries and followed for 13.9 years on average. Hazard ratios (HR) for developing urothelial cell carcinoma (UCC; 1,802 incident cases) were calculated using Cox proportional hazards models. Alcohol consumption at baseline and over the life course was analyzed, as well as different types of beverages (beer, wine, spirits). Baseline alcohol intake was associated with a statistically nonsignificant increased risk of UCC (HR 1.03; 95% confidence interval (CI) 1.00-1.06 for each additional 12 g/day). HR in smokers was 1.04 (95% CI 1.01-1.07). Men reporting high baseline intakes of alcohol (>96 g/day) had an increased risk of UCC (HR 1.57; 95% CI 1.03-2.40) compared to those reporting moderate intakes (<6 g/day), but no dose-response relationship emerged. In men, an increased risk of aggressive forms of UCC was observed even at lower doses (>6 to 24 g/day). Average lifelong alcohol intake was not associated with the risk of UCC, however intakes of spirits > 24 g/day were associated with an increased risk of UCC in men (1.38; 95% CI 1.01-1.91) and smokers (1.39; 95% CI 1.01-1.92), compared to moderate intakes. We found no association between alcohol and UCC in women and never smokers. In conclusion, we observed some associations between alcohol and UCC in men and in smokers, possibly because of residual confounding by tobacco smoking.	bladder
Tuberculous Psoas Abscess and Worsening Vascular Aneurysm; All from Bacillus Calmette-Guerin (BCG) Therapy?	BACKGROUND Intravesical bacillus Calmette-Guerin (BCG) is used in the treatment and prophylaxis of carcinoma in situ of the urinary bladder and for the prophylaxis of primary or recurrent stage Ta and T1 papillary tumors following transurethral resection. Significant systemic complications are rare but have been reported. CASE REPORT We describe this case of Mycobacterium bovis psoas abscess and worsening abdominal aortic aneurysm following BCG therapy for bladder cancer. A 76-year-old male presented with a fever of a few days. He had a computed tomography (CT) scan of abdomen and pelvis that showed left iliopsoas fluid collection measuring 6.7×3.8 cm and an abdominal aortic aneurysm that had almost doubled in size from 4.9 cm to 8.5 cm. The patient underwent CT-guided aspiration of the iliopsoas collection. Mycobacterium bovis was isolated from the aspirate cultures. He had received intravesical BCG therapy for bladder cancer a few years prior. CONCLUSIONS The rapid increase in the size of the abdominal aortic aneurysm (mycotic aneurysm) in our patient was most likely due to BCG therapy. The risk-benefit assessment of this treatment should be carefully considered especially in patients with a pre-existing vascular aneurysm.	bladder
MicroRNAs with prognostic significance in bladder cancer: a systematic review and meta-analysis.	The aim of this study was to systematically review articles that investigated the prognostic significance of different microRNAs in bladder cancer (BC). We systematically searched PubMed, Web of Science, and Embase to identify relevant studies until March 2016. After screening, 26 studies that involved 2753 patients were included. Results suggested that many miRs expression aberration may predict prognosis in patients with BC. There are six miRs (miR-21, miR-143, miR-155, miR-200, miR-214, and miR-222) were reported by at least two studies, and we performed meta-analysis in the corresponding studies. Accordingly, we found that high miR-21 expression was associated with poor overall survival [OS; hazard ratio (HR) = 3.94, 95% CI 2.08-7.44]. High miR-143 expression was associated with poor progression-free survival (PFS; HR = 3.78, 95% CI 1.61-8.89). High miR-155 expression was associated with poor PFS (HR = 8.10, 95% CI 2.92-22.48). High miR-222 expression was associated with poor OS (HR = 3.39, 95% CI 1.10-10.41). Meanwhile, low miR-214 expression was correlated with poor RFS(HR = 0.34, 95% CI 0.22-0.53). Our comprehensive systematic review concluded that microRNAs, particularly miR-21, miR-143, miR-155, miR-214, and miR-222, could serve as meticulous follow-up markers for early detection of progression or recurrence and even useful therapeutic targets for the treatment in patients with BC.	bladder
STOP smoking and alcohol drinking before OPeration for bladder cancer ﻿(the STOP-OP study),﻿ perioperative smoking and alcohol cessation intervention in relation to radical cystectomy: study protocol for a randomised controlled trial.	BACKGROUND: To evaluate the effect of a smoking-, alcohol- or combined-cessation intervention starting shortly before surgery and lasting 6 weeks on overall complications after radical cystectomy. Secondary objectives are to examine the effect on types and grades of complications, smoking cessation and alcohol cessation, length of hospital stay, health-related quality of life and return to work or habitual level of activity up to 12 months postoperatively. METHODS/DESIGN: The study is a multi-institutional randomised clinical trial involving 110 patients with a risky alcohol intake and daily smoking who are scheduled for radical cystectomy. Patients will be randomised to the 6-week Gold Standard Programme (GSP) or treatment as usual (control). The GSP combines patient education and pharmacologic strategies. Smoking and alcohol intake is biochemically validated (blood, urine and breath tests) at the weekly meetings and at follow-up. DISCUSSION: Herein, we report the design of the STOP-OP study, objectives and accrual up-date. This study will provide new knowledge about how to prevent smoking and alcohol-related postoperative complications at the time of bladder cancer surgery. Till now 77 patients have been enrolled. Patient accrual is expected to be finalised before the end of 2017 and data will be published in 2018. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02188446 . Registered on 28 May 2014.	bladder
Superantigen staphylococcal enterotoxin C1 inhibits the growth of bladder cancer.	Superantigens can induce cell-mediated cytotoxicity preferentially against MHC II-positive target cells with large amounts of inflammatory cytokines releasing. In this study, superantigen staphylococcal enterotoxin C (SEC) 1 was investigated to evaluate its potential in bladder cancer immunotherapy in vitro and in vivo. Our results revealed that SEC1 could stimulate the proliferation of human peripheral blood mononuclear cells (PBMCs) in a dose-dependent manner, accompanied with the release of interleukin-2, interferon-γ, and tumor necrosis factor-α, and increased the population of CD4(+) T cells and CD8(+) T cells. PBMCs stimulated by SEC1 could initiate significant cytotoxicity towards human bladder cancer cells in vitro. The results of in vivo antitumor experiment indicated that SEC1 could decrease the rate of tumor formation and prolong the survival time of tumor-bearing mice. Our study demonstrated that SEC1 inhibited the growth of bladder cancer. And it is also suggested that SEC1 may become a candidate for bladder cancer immunotherapy.	bladder
Cordycepin induces apoptosis in human bladder cancer cells via activation of A3 adenosine receptors.	Bladder cancer is a neoplasm originated from bladder epithelial cells. The therapy for bladder cancer is so far not satisfactory. In this study, we examined the effects of Cordyceps militaris hot water extracts containing cordycepin on human bladder cells. Cordyceps militaris hot water extracts containing cordycepin was used to treat human T24 bladder carcinoma cells, and we found that Cordyceps militaris hot water extracts containing cordycepin decreased T24 cell survival in a dose-dependent manner, which was seemingly mediated by activation of A3 adenosine receptor and the subsequent inactivation of Akt pathways, resulting in increases in cleaved Caspase-3 and apoptosis. Overexpression of A3 adenosine receptor in T24 cells mimicked the effects of Cordyceps militaris hot water extracts, while A3 adenosine receptor depletion abolished the effects of Cordyceps militaris hot water extracts containing cordycepin. Together, these data suggest that Cordyceps militaris hot water extracts containing cordycepin may be a promising treatment for bladder cancer via A3 adenosine receptor activation.	bladder
Health information quality on the internet for bladder cancer and urinary diversion: a multi-lingual analysis.	"INTRODUCTION: Bladder cancer patients undergoing radical cystectomy and urinary diversion are faced with difficult decisions regarding mode of urinary diversion. Although these patients may use the Internet as a guide to diagnosis and treatment options, online resources remain largely unregulated leading to a great variation in quality of medical information. Further variation in quality is seen between languages. Fortunately, tools such as an automated toolbar developed by the World Health Organization Health on the Net (HON) Foundation exist to assist physicians in recommending quality online health information to patients. We set out to compare and assess the quality of bladder cancer, ileal conduit and orthotopic neobladder web sites in 2016 on the basis of the HON principles for English language. EVIDENCE ACQUISITION: The Google search engine imbedded with the HON toolbar was used to assess 1350 Web sites using the keywords ""bladder cancer"", ""ileal conduit"" and ""orthotopic neobladder"" in English, Italian and Spanish. The first 150 results of each search were identified and screened. A further analysis was completed comparing results between 2009 and 2016. EVIDENCE SYNTHESIS: Less than 20% of English, Italian and Spanish ""bladder cancer"" and urinary diversion (""ileal conduit"" and ""orthotopic neobladder"") web sites are HON-accredited. HON-accredited web sites featured preferentially in the first 50 search results for bladder cancer (P=0.0001) and ileal conduit (P=0.03) web sites. Comparing 2016 results to 2009, percentage of HON-accreditation has not shown statistically significant change (-13%, P=0.23), while overall number of search results has increased (+44%). CONCLUSIONS: A lack of validation of bladder cancer sites is present, which is consistent across modes of urinary diversion (orthotopic neobladder and ileal conduit) and languages. It is important that physicians involved in the care of bladder cancer patients undergoing radical cystectomy and urinary diversion participate in the development of informative, ethical, and reliable health Web sites and direct patients to them."	bladder
Long noncoding RNA linc00346 promotes the malignant phenotypes of bladder cancer.	BACKGROUND: More and more reports have demonstrated that long noncoding RNAs (lncRNAs) play an important role in the development of a variety of carcinomas, including bladder cancer. However, only a small fraction of them have been characterized. Linc00346 have been found to be upregulated in bladder cancer tissues compared to normal tissues in a microarray-based lncRNA profiling study. In this study, we would like to explore the expression pattern and functional role of linc00346 in bladder cancer. METHODS: We determined the expression of linc00346 in a cohort of bladder cancer tissues with matched normal tissues as well as human bladder cancer cell lines. We investigated the biological function of linc00346 with CCK-8 assay, colony formation assay, flow cytometry analysis, transwell assay and tumor xenografts mice model. RESULTS: We found that linc00346 was upregulated in bladder cancer tissues compared to normal tissues. Knockdown of linc00346 inhibited bladder cancer cell proliferation and migration, induced cell cycle arrest and cell apoptosis. CONCLUSION: Our study demonstrates that linc00346 could be a potential oncogene and a therapeutic target in bladder cancer.	bladder
